Abstract :

In this paper to predict the critical conditions for onset of elastic-plastic wrinkling of flange of a two-layered circular blank during the deep-drawing process a closed-form semi-analytical elastic-plastic solution using tresca yield criterion along with deformation theory in plasticity with considering the perfectly plastic behavior of materials is presented. Simplifying the presented solution from two layered to one layered the results exactly agree with the previous work done by the authors.
